To all whom t may concern.'-

Beit known that I, WILLIAM GossHonN, of Waterloo, in the county of Juniata and State of Pennsylvania, have invented a new and ImprovedFlour-Bolt, of which the following is a specification In theaccompanying drawing, Figure 1 represents a vertical central 4section of.my i1nproved upright iour-bolt on the line c c, Fig. 2, and Fig. 2, ahorizontal section of the same on the line x m, Fig. l.

'The meal is introducedto it by apertures l of the top part b, and bolted by thecentrifugalforce imparted by the rotation of fan B, the bran passing out throughthe open bottom b.

The distribution of the flour in boltin g brings it in contact with theair, so that it cools at the same time. The fiour is also bolted a greatdeal faster and cleaner than with the old reels, as no clogging can takeplace in the fan-bolt. No flour, middlings, or bran settles in the clothor bolt 0n account of its upright position 5 con sequently mothsorinsects have no chance to cut and destroy the stationary cloth, sothat it lasts a considerably longer period of time than the `cloth onthe old reels, which arecut by the
